SIP ALG allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are having trouble making VoIP calls, try turning this ALG off.

Step 1: Open a web browser and enter http://dlinkrouter.local. or http://192.168.0.1 into the address bar. Enter your password and click Log In.

Step 2: Go to Features and then click Firewall. Click Advanced Settings and then click SIP to disable it.

IMPORTANT: D-Link does not guarantee the compatibility of all USB storage devices.

Step 1: Open your web browser and type in http://dlinkrouter.local. or type in the IP address of the router (default – http://192.168.0.1).

Step 2: Enter or select the username (admin) and enter your password (blank by default), and then click OK or Log In. The password is case-sensitive.

If you forgot your password, you will need to reset the router back to the factory default settings. Unfortunately this will remove any settings you have and you will need to reconfigure your router.

To reset your router, use a paper clip and press & hold the reset button (usually located on the back of the router) for 10 seconds and release. Allow 1 minute to reboot. The default IP address of the router will be 192.168.0.1and the password is blank.

If you are connecting wirelessly, you will need to reconnect your device to the default wireless network after the router reboots. The default Wi-Fi network/password may be printed on the label on the bottom of the router or on the included Wi-Fi Configuration Card (newer models).

To reconfigure, refer to the Quick Install Guide included with your router or download the PDF (click Close and then click Downloads).

QoS (Quality of Service) is designed to shape and prioritize your internet traffic among the computers on your LAN. This allows for an optimized internet experience.

To set up QoS in your router, use the following steps:

Step 1: Open a web browser and type the IP address of the DIR series router into the address bar (default is http://192.168.0.1).

Step 2: The default username is admin (all lower case) and the default password is blank (nothing). Click on OK.

Step 3: Click on the Advanced tab at the top and then click on QOS Engine on the left hand side.

WAN TRAFFIC SHAPING

Enable QoS Engine: Enable this option for better performance and experience with online games and other interactive applications, such as VoIP.

Automatic Uplink Speed: When enabled, this option causes the router to automatically measure the useful uplink bandwidth each time the WAN interface is re-established (after a reboot, for example).

Measured Uplink Speed: This is the uplink speed measured when the WAN interface was last re-established. The value may be lower than that reported by your ISP as it does not include all of the network protocol overheads associated with your ISP’s network. Typically, this figure will be between 87% and 91% of the stated uplink speed for xDSL connections and around 5 kbps lower for cable network connections.

Manual Uplink Speed: If Automatic Uplink Speed is disabled, this option allows you to set the uplink speed manually. Uplink speed is the speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISPs often specify speed as a downlink/uplink pair; for example, 1.5Mbps/284kbps. For this example, you would enter “284”. Alternatively you can test your uplink speed with a service such as www.dslreports.com. Note however that sites such as DSL Reports, because they do not consider as many network protocol overheads, will generally note speeds slightly lower than the Measured Uplink Speed or the ISP rated speed.

On some mobile devices, when connected with the D-Link DIR-890L over wi-fi, may take a considerable time duration to load webpages. This is affecting customers using some internet service providers and not others. The current work around is to follow the instructions below to disable IPv6 on your Wide Area Network (WAN) port. CAUTION: (this is only possible if you are currently obtaining access to the internet using IPv4 addressing)

Step 1: Open your Internet browser and type the IP address of the router or friendly DNS name (FDNS) in the address bar. The default IP address is http://192.168.0.1 and the default FDNS name is “http://dlinkrouter.local”. At the login, enter your password (default password is blank). Use the password set at the initial installation to login to a previously configured D-Link router.

Step 5: Click on Save. This will save your settings. Your router will reconfigure it’s internet settings to have IPv6 removed from the WAN port. There will be a momentary disconnect from the internet as your router completes the changes.

Verification: When your router has completed the changes, test your mobile device’s load speed of web pages and check for an improvement.
